Detailed Description
A base color, one value in range 0..1.0 for each channel of a ColorSystem.
Member Function Documentation

Return the alpha of the color. 1==totally opaque, 0==totally transparent, -1==no alpha.
If the ColorSystem defines alpha within the primaries, then either that alpha is used in place of this->alpha, but only if this->alpha is not within range 0..1.0. If alpha is in range, then the returned alpha is that multiplied by the system channel. If the system has no built in alpha, then this->alpha is returned.

Return the value of channel.
This function does no checking against system. It only checks channel against this->n, and returns values[channel].
On error -1 is returned.
Return the value of channel as an int in the range of the primary of the ColorSystem.
On error, -1 is returned, and error_ret set to a nonzero number: 1 means no system specified, 2 means channel out of range, 3 means values[channel] is not in range 0 to 1.0. If channel doesn't exist. This assumes that system exists to be queried about primary limits.
